Spiral Flush-Trim Router Bits，Solid Carbide Flush Trim Router Bit 1/4-Inch Shank Spiral Flush Trim Up Cut from TACKPRO (1/4 Shank Up-Cut)

Cut very clean and without a lot of drag on the router motor...this is partially due to the small diameter, but also a sign of good design and sharp cutting edges.

The bit snapped in half during first use. Still not able to find the other half. No injuries, so could have been much worse, but not impressed.

Shipping to South Africa is a nag and takes forever but product is exceptional.

Definitely one of my favorite bits. Such a clean finish!

I broke the first bit that was sent to me, but its because I didnt understand exactly what part of the bit could actually cut. At the top of the bit (the end that connects to the router), its solid cylindrical metal until you get to the point where the spiral groove starts to be cut into the shaft. That area cannot cut through the wood. Its not until you get a little further toward the bearing end that you get to the actually cutting area of the bit. I didnt realize this and was trying to cut plywood partially with that non-cutting area. It took a lot of force and ultimately the bit broke. Now that I understand, my replacement bit is working great. Ive seen a couple people complain about breaking bits, and I have to wonder if they did the same thing I did. Prior to this bit, I was using a 1/2 straight bit. It did the job, but it was a lot more work pushing it through, and the resulting cut was kind of rough. Needed a good deal of sanding. With this spiral bit, the cut is smooth as glass.

WORKS GREAT with my dewalt drill. Easily cut through drywall and 1/2 inch plywood. By far a great investment. Used for 2 days straigh and bit is still sharp. Cuts are clean and concise.

was a little apprehensive on the 1/4 shank size -- had been using a 1/2 shank but it got $$$ -- this bit worked perfect in a template routing project to cut a hole in the middle of a 7/8 piece of walnut -- took a little longer but one side of the hole is only 1/2 from the edge i think the smaller bite of the bite is better -- will order more

The bit was packaged well and protected against damage. Upon initial inspection one of the two guide bearings was not spinning freely. It had a catch similar to a bad bearing. After the first use it was obvious the bearing was bad as it was marring the template. The bit cut very cleanly and overall meets the price point in comparison to some other name brand tooling.

Used it to cut plywood out in window opening made it 2 inches snapped but it was a quick 2 inches. Disappointed to say the least.

I just used it today. For the money you can’t beat it very happy with it so far leaves a nice finish on the work peace.
